I have an SRAM PC48 chain that I need to add a few links to now that I have a new, larger rear derailleur. I have the links that I originally removed from this chain recently, and thought it wouldn't be a big deal to add them back on - I've done such a thing in the past to other chains and it wasn't challenging. Today, as I'm trying to add the links, they're going on too tight/pinched such that it's seizing. I've removed and re-added a couple of times now, and just can't seem to get it right. I tried connecting two extra links off of my main chain to practice, and got them on 'normally' just once, after 3 tries, and I can't tell what I did different. Is there some trick?
